Composite material sample preparation mold and method, sample and strength test method thereof
The invention relates to a composite material sample preparation mold and method and a sample and a strength testing method thereof.The mold comprises a first mold body and a second mold body, the first mold body is provided with a first pouring cavity, and the first mold body is further provided with a plurality of first fixing cavities penetrating through the outer wall of the first mold body and communicated with the pouring cavity; the side wall of the first fixing cavity limits horizontal movement of glass fibers so as to fix the ends of the glass fibers, the diameter of the first fixing cavity ranges from 1 mm to 2.5 mm, the diameter of the first fixing cavity is slightly larger than that of the glass fibers, the first mold body is further provided with a pouring channel communicated with the first pouring cavity, and the second mold body is provided with a second pouring cavity. And when the first mold body and the second mold body are combined, the first filling cavity and the second filling cavity are coaxial and jointly form a closed sample cavity. The composite material sample preparation mold can overcome the defects that the glass fiber is easy to break, the test difficulty is high and the cost is high when the interface strength between the glass fiber and the matrix resin is tested in the prior art.
本发明涉及一种复合材料样品制备模具和方法及样品及其强度测试方法，其中的模具包括第一模具本体和第二模具本体，第一模具本体设有第一灌注腔，第一模具本体还设有多个穿过其外壁并与灌注腔相通的第一固定腔，第一固定腔的侧壁限制玻璃纤维的水平移动从而固定玻璃纤维的端部，第一固定腔的直径为1mm—2.5mm，第一固定腔的直径略大于玻璃纤维的直径，第一模具本体还设有与第一灌注腔相通的灌注通道，第二模具本体设有第二灌注腔，在第一模具本体与第二模具本体合并时，第一灌注腔与第二灌注腔同轴且共同形成封闭的样品腔。本发明的复合材料样品制备模具可以克服现有的玻璃纤维与基体树脂之间的界面强度测试时玻璃纤维易断、测试难度大且成本高的缺点。
