Aug 28, 2019 Compressive strengths are usually reported in relationship to a specific technical standard. Concrete and ceramics typically have much higher compressive strengths than those with high tensile strengths. Composite materials, such as glass fiber epoxy matrix composite, tend to have higher tensile strengths than compressive strengths.

Therefore, the compressive strength of a material is usually stated as the maximum compression that the material can stand before failure. Materials which can resist high, applied compressive forces before failure are said to have high compressive strengths. Some materials are better than others at withstanding compression before failure occurs.
